Studying Migrant Assimilation Through Facebook Interests

Migrants' assimilation is a major challenge for European societies, in part because of the sudden surge of refugees in recent years and in part because of long-term demographic trends. In this paper, we use Facebook's data for advertisers to study the levels of assimilation of Arabic-speaking migrants in Germany, as seen through the interests they express online. Our results indicate a gradient of assimilation along demographic lines, language spoken and country of origin. Given the difficulty to collect timely migration data, in particular for traits related to cultural assimilation, the methods that we develop and the results that we provide open new lines of research that computational social scientists are well-positioned to address.Comment: Accepted as a short paper at Social Informatics 2018 (https://socinfo2018.hse.ru/).

Streamline topology and dilute particle dynamics in a Karman vortex street flow

Three types of streamline topology in a Karman vortex street flow are shown under the variation of spatial parameters. For the motion of dilute particles in the K\'arm\'an vortex street flow, there exist a route of bifurcation to a chaotic orbit and more attractors in a bifurcation diagram for the proportion of particle density to fluid density. Along with the increase of spatial parameters in the flow filed, the bifurcation process is suspended, as well as more and more attractors emerge. In the motion of dilute particles, a drag term and gravity term dominate and result in the bifurcation phenomenon.Comment: 16 pages, 9 figure

Refinement of Techniques Metallographic Analysis of Highly Dispersed Structures

Flaws are regularly made while developing standards and technical specifications. They can come out as minor misprints, as an insufficient description of a technique. In spite the fact that the flaws are well known, it does not come to the stage of introducing changes to standards. In this paper shows that in the normative documents is necessary to clarify the requirements for metallurgical microscopes, which are used for analysis of finely-dispersed

Rotation numbers of invariant manifolds around unstable periodic orbits for the diamagnetic Kepler problem

In this paper, a method to construct topological template in terms of symbolic dynamics for the diamagnetic Kepler problem is proposed. To confirm the topological template, rotation numbers of invariant manifolds around unstable periodic orbits in a phase space are taken as an object of comparison. The rotation numbers are determined from the definition and connected with symbolic sequences encoding the periodic orbits in a reduced Poincar\'e section. Only symbolic codes with inverse ordering in the forward mapping can contribute to the rotation of invariant manifolds around the periodic orbits. By using symbolic ordering, the reduced Poincar\'e section is constricted along stable manifolds and a topological template, which preserves the ordering of forward sequences and can be used to extract the rotation numbers, is established. The rotation numbers computed from the topological template are the same as those computed from their original definition.Comment: 8 figures, 1 tabl

1960 Homecoming Program and 1916-1917 Class Reunion

This printed program was compiled for the Jacksonville State College Homecoming festivities in October 1960. As part of the activities, a class reunion was held October 7-8 for the State Normal School alumni from the 1916-1917 class and also the football teams of 1913-1918. Photographs of the alumni are included, along with a transcript of a speech given by R. Liston Crow, a S.N.S. alumnus who later served as treasurer at JSU. The speech details the lives and careers of many of the members of the Class of 1916-1917, along with school memories. The originals of the printed program and speech notes are held in the Crow Collection of Anniston-Calhoun County Public Library; ACCPL temporarily loaned the materials from which HCL created these digital surrogates.https://digitalcommons.jsu.edu/lib_ac_unihist_misc/1011/thumbnail.jp

W.R. Walter Correspondence

Entries include the brief biographical information of a poet from North Waldoboro, Maine, and his droll and engaging typed biographical letter of reply to the Maine State Library concerning early farm work, a Maine district education system based on student enrollment wherein Walter once had six weeks of school in one year, and the family lumber mill business, typed correspondence concerning Walter\u27s book gift of Life\u27s poems with a foreword by Rev. George B. Davis, and a typed letter from the Maine State Library on receipt of Walter\u27s biography

Automated labeling of unknown contracts in Ethereum

yesSmart contracts have recently attracted interest from diverse fields including law and finance. Ethereum in particular has grown rapidly to accommodate an entire ecosystem of contracts which run using its own crypto-currency. Smart contract developers can opt to verify their contracts so that any user can inspect and audit the code before executing the contract. However, the huge numbers of deployed smart contracts and the lack of supporting tools for the analysis of smart contracts makes it very challenging to get insights into this eco-environment, where code gets executed through transactions performing value transfer of a crypto-currency. We address this problem and report on the use of unsupervised clustering techniques and a seed set of verified contracts, in this work we propose a framework to group together similar contracts within the Ethereum network using only the contracts publicly available compiled code. We report qualitative and quantitative results on a dataset and provide the dataset and project code to the research community.Link to conference webpage: http://icccn.org/icccn17/workshop

One Hundred Years of Street Photography

A program from an exhibition featuring street photography from a variety of artists including but not limited to Diane Arbus, Alfred Stieglitz, Henri Cartie Bresson, and many more. One Hundred Years of Street Photography ran from February 20 through April 3, 1994. The catalog for this exhibition was originally available via CD-ROM.https://corescholar.libraries.wright.edu/restein_catalogs/1049/thumbnail.jp

Water Being Water

IQ. DNA. MRI. FYI. In an ever-changing world, we find ourselves conversing with abbreviated acronyms and phrases. They drive today\u27s economy, political agenda, and water cooler chitchat. They define our use of resources and the attention given to matters. Who we are, or think we are, are wrapped around their brevity. In our hurried attempt to sort through the complexities of life we use them to only answer the obvious-How? Unfortunately, an equally important question, Why? is often ignored. The solving of the how of things has generally been left to the scientists and the reasons as to the why for artists to decipher. This publication and exhibition takes a new approach by making the two questions inseparable. Using the simplest of elements, H20, a scientist turned artist, and two writers, one from the sciences and the other from the arts, have begun a new conversation. It is a discussion that deserves our attention and participation.https://corescholar.libraries.wright.edu/restein_catalogs/1051/thumbnail.jp

Knowledge Transfer and Teaching Public Administration: the Academy Model

Since the beginnings of Public Administration in the US and its accompanying education in other parts of the world, government and policy have become more complex. The education in Public Administration created a professional pathway to public service. The addition of education to Public Administration came out of the Progressive Movement in the United States to make knowledge in Public Administration more important in the face of corruption brought on by patronage appointments. When nonprofits became part the US public sector as elsewhere along with nonprofit healthcare, the complexity expanded enormously, requiring professionals to know more in what has become a multidisciplinary field of study. Given the diversity and complexity of the public sector and the need for Public Administration to embrace more knowledge from many disciplines, it stands to reason that an earlier start on the education portion of Public Administration or a pathway would be beneficial. A model of early Public Administration knowledge transfer is described and illustrated below. The Academy described is based on the US career pathways and high school academies as part of the school to work educational movement. The success of the combination of these two areas will also be pointed out in the academy described. Translation of lessons learned from the Acdemy to Europe and Asia are also considered
